Simulation Research in Gastrointestinal and Urologic Care-Challenges and Opportunities: Summary of a National Institute of Diabetes and Digestive and Kidney Diseases and National Institute of Biomedical Imaging and Bioengineering Workshop

Effects of cooperative nursing and patient education on postoperative infection and self-efficacy in gastrointestinal tumors

BACKGROUND

Gastrointestinal tumors have a high incidence rate. The application value of the cooperative nursing care system of medical care has received widespread attention in recent years. However, there are few studies on the value of the joint application of collaborative nursing care and self-efficacy education.

AIM

To explore the effect of cooperative nursing care management/self-efficacy education on postoperative infection and self-efficacy in gastrointestinal tumor surgery patients.

METHODS

A total of 102 patients with gastrointestinal tumors treated in our hospital from October 2018 to February 2020 were selected and divided into a conventional group (n = 51) and a combined group (n = 51) according to the nursing plan. The routine group adopted routine nursing, and the joint group adopted the medical care cooperative responsibility system nursing management combined with self-efficacy education. The self-efficacy scores, coping style scores, self-experience burden scores, and postoperative complication rates of the two groups before and after intervention were counted.

RESULTS

After intervention, the daily life behavior management, cognitive symptom management, and disease management scores of the two groups were higher than those before the intervention, and those of the combined group were higher than those of the conventional group (all P = 0.000). After the intervention, the positive response scores of the two groups were higher than those before the intervention, the negative response scores were lower than those before the intervention, and the combined group was better than the conventional group (all P = 0.000). After the intervention, the two groups’ emotional, economic, and physical factor scores were lower than those before the intervention, and the combined group was lower than the conventional group (all P = 0.000). The incidence of infection in the combined group (1.96%) was lower than that in the conventional group (15.69%) (P = 0.036).

CONCLUSION

Cooperative nursing care management and self-efficacy education improved the physical and mental states of gastrointestinal cancer surgery patients, change the response to disease, and reduce the risk of postoperative infection.

Segmentation of Temporal Bone Anatomy for Patient-Specific Virtual Reality Simulation

Objectives:

Virtual reality (VR) simulation for patient-specific pre-surgical planning and rehearsal requires accurate segmentation of key surgical landmark structures such as the facial nerve, ossicles, and cochlea. The aim of this study was to explore different approaches to segmentation of temporal bone surgical anatomy for patient-specific VR simulation.

Methods:

De-identified, clinical computed tomography imaging of 9 pediatric patients aged 3 months to 12 years were obtained retrospectively. The patients represented normal anatomy and key structures were manually segmented using open source software. The OTOPLAN (CAScination AG, Bern, Switzerland) otological planning software was used for guided segmentation. An atlas-based algorithm was used for computerized, automated segmentation. Experience with the different approaches as well as time and resulting models were compared.

Results:

Manual segmentation was time consuming but also the most flexible. The OTOPLAN software is not designed specifically for our purpose and therefore the number of structures that can be segmented is limited, there was some user-to-user variation as well as volume differences compared with manual segmentation. The atlas-based automated segmentation potentially allows a full range of structures to be segmented and produces segmentations comparable to those of manual segmentation with a processing time that is acceptable because of the minimal user interaction.

Conclusion:

Segmentation is fundamental for patient-specific VR simulation for pre-surgical planning and rehearsal in temporal bone surgery. The automated segmentation algorithm currently offers the most flexible and feasible approach and should be implemented. Further research is needed in relation to cases of abnormal anatomy.

ASGE EndoVators Summit: simulators and the future of endoscopic training

Interest in the use of simulation for acquiring, maintaining, and assessing skills in GI endoscopy has grown over the past decade, as evidenced by recent American Society for Gastrointestinal Endoscopy (ASGE) guidelines encouraging the use of endoscopy simulation training and its incorporation into training standards by a key accreditation organization. An EndoVators Summit, partially supported by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health, (NIH) was held at the ASGE Institute for Training and Technology from November 19 to 20, 2017. The summit brought together over 70 thought leaders in simulation research and simulator development and key decision makers from industry. Proceedings opened with a historical review of the role of simulation in medicine and an outline of priority areas related to the emerging role of simulation training within medicine broadly. Subsequent sessions addressed the summit's purposes: to review the current state of endoscopy simulation and the role it could play in endoscopic training, to define the role and value of simulators in the future of endoscopic training and to reach consensus regarding priority areas for simulation-related education and research and simulator development. This white paper provides an overview of the central points raised by presenters, synthesizes the discussions on the key issues under consideration, and outlines actionable items and/or areas of consensus reached by summit participants and society leadership pertinent to each session. The goal was to provide a working roadmap for the developers of simulators, the investigators who strive to define the optimal use of endoscopy-related simulation and assess its impact on educational outcomes and health care quality, and the educators who seek to enhance integration of simulation into training and practice.
